“We took the allegation very seriously and took immediate action. We met with the accuser twice and had repeated communications with him. We met with Kevin, who denied the accusation. We also conducted a thorough investigation and found the allegation of underage conduct to be unsubstantiated. Although this was a personal relationship unrelated to the workplace, our investigation did reveal that Kevin exercised poor judgment and violated company policy regarding internet usage and he was disciplined,” the Sesame Street Workshop statement said.

“Kevin insists that the allegation of underage conduct is false and defamatory and he is taking actions to protect his reputation. We have granted him a leave of absence to do so.

“Elmo is bigger than any one person and will continue to be an integral part of Sesame Street to engage, educate and inspire children around the world, as it has for 40 years.”

CNN could not reach Clash immediately for a response. TMZ reported that Clash said his relationship with the accuser “was between two consenting adults and I am deeply saddened that he is trying to make it into something it was not.”

Clash, 52, has won Emmy Awards for his work on Sesame Street.

In an interview previously posted on the website of NYC Dads, an initiative of New York Mayor Michael Bloomberg, he spoke about how he worked to spend time with his daughter, who lives with his ex-wife outside of Baltimore.
